For engineers reviewing the R5F56609CGFP#30 datasheet, R5F56609CGFP#30 pinout, R5F56609CGFP#30 application, or R5F56609CGFP#30 equivalent, key selection considerations include its 144-pin LFQFP (PLQP0144KA-B) package, G-grade temperature range (–40°C to +105°C), sub-clock oscillator support for RTC operation, JTAG/FINE debug interfaces, and IEC60730 safety features including MPU, CAC, CRCA, and register write protection.

Technical Context

The R5F56609CGFP#30 implements the RXv3 CPU core with single-precision FPU compliant to IEEE 754, collective register bank save, and memory protection unit (MPU) supporting eight configurable protection areas down to 16-byte granularity. It integrates a 120-MHz system clock (ICLK), dual PLL paths (main clock oscillator + HOCO reference), and independent peripheral clocks (PCLKA up to 120 MHz, PCLKB up to 60 MHz, ADCLK up to 60 MHz).

Its event-linking controller (ELC) enables 83 internal event signals to trigger peripheral operations-including MTU3a PWM generation, S12ADH conversion starts, and IWDT refresh-without CPU intervention. The device supports deep software standby mode with RTC active, four low-power modes, and hardware-assisted safety functions including oscillation-stop detection, RAM test assistance via DOC, and self-diagnostic A/D disconnection detection.

FAQ

What is the maximum operating frequency and core architecture of the R5F56609CGFP#30?

The R5F56609CGFP#30 operates at a maximum frequency of 120 MHz using the 32-bit RXv3 CPU core with integrated single-precision floating-point unit (FPU) compliant to IEEE 754. It achieves 709 CoreMark score at full speed and supports collective register bank save, memory protection unit (MPU), and 113 instructions including DSP and FPU extensions. This architecture enables deterministic real-time control in motor drives and industrial automation where computational throughput and low-latency interrupt response are critical.

Does the R5F56609CGFP#30 support CAN FD, and what protocol standard does it comply with?

Yes, the R5F56609CGFP#30 integrates one CAN FD module compliant with ISO 11898-1:2015, supporting both standard (11-bit) and extended (29-bit) frame formats with data rates up to 5 Mbps in the data phase. The module includes message RAM with configurable FIFOs, error counters, and loopback/self-test modes. Its implementation in the R5F56609CGFP#30 enables high-bandwidth diagnostics and firmware updates in industrial networks where legacy CAN 2.0B bandwidth limitations impede system scalability.

What are the analog capabilities of the R5F56609CGFP#30, particularly regarding ADC and DAC?

The R5F56609CGFP#30 includes a 24-channel 12-bit S12ADH analog-to-digital converter with minimum 0.9 µs conversion time at 60 MHz ADCLK, and two 12-bit R12DAb digital-to-analog converters with 0–AVCC0 output range. The ADC supports group scan prioritization, self-diagnosis, and analog input disconnection detection; the DAC outputs can serve as reference voltages for the four-channel CMPC comparators. These capabilities make the R5F56609CGFP#30 suitable for closed-loop analog control in HVAC and power conversion where simultaneous high-resolution sensing and actuation are required.

How does the R5F56609CGFP#30 support functional safety standards like IEC60730?

The R5F56609CGFP#30 incorporates multiple hardware-based IEC60730 Class B compliance features: oscillation-stoppage detection for main/sub-clock oscillators, clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA) for memory/data integrity, register write protection, RAM test assistance via DOC, and independent watchdog timer (IWDT) with window function. These are documented in the R01DS0393EJ0100 datasheet and enable systematic safety mechanisms without requiring external components - reducing certification effort for household appliances and industrial controls where self-test coverage and fault detection are mandated.

What package type and temperature grade does the R5F56609CGFP#30 use?

The R5F56609CGFP#30 uses a 144-pin Low-profile Quad Flat Package (LFQFP) with PLQP0144KA-B footprint (20 × 20 mm, 0.5 mm pitch) and is rated for the G-grade industrial temperature range of –40°C to +105°C. It includes both JTAG and FINE debugging interfaces and supports the sub-clock oscillator for RTC operation - distinguishing it from D-grade variants and non-sub-clock versions in the RX660 family. This package enables high I/O count (130 GPIOs) with 5-V tolerant pins for direct interfacing to industrial sensors and actuators.
